Descripción detallada de la invenciónDetailed description of the invention

En el ejemplo de realización mostrado en las figuras, la forma en planta de la pieza de transición (2) es cuadrada. Sin embargo, otras formas, por ejemplo, una planta triangular equilátera (sistema de tres patas), podrían ser también empleadas. In the exemplary embodiment shown in the figures, the plan shape of the transition piece (2) is square. However, other forms, for example, an equilateral triangular plant (three-legged system), could also be employed.

En el ejemplo de realización correspondiente a la figura 1, la estructura de celosía (1) (“Jacket”) es de cuatro patas verticales con un ángulo de inclinación de 0°, donde las piezas diagonales forman una X con crucetas dispuestas a espacios iguales.In the example of embodiment corresponding to Figure 1, the lattice structure (1) ("Jacket") is four vertical legs with an inclination angle of 0 °, where the diagonal pieces form an X with crosspieces arranged in equal spaces .

El ejemplo de realización de la pieza de transición (2) representada en la figura 3 comprende:The exemplary embodiment of the transition piece (2) shown in Figure 3 comprises:

- la cubierta inferior (3),- the lower cover (3),

- la pieza cilíndrica (5) centrada en la cubierta inferior (3), es decir, en el centro de la pieza de transición (2),- the cylindrical part (5) centered on the lower cover (3), that is, in the center of the transition piece (2),

- ocho mamparos radiales (4),- eight radial bulkheads (4),

- el conjunto envolvente exterior (7) localizado en el contorno exterior de la pieza de transición (2) y que se disponen verticalmente,- the outer envelope assembly (7) located on the outer contour of the transition piece (2) and arranged vertically,

la cubierta superior (6) situada sobre los mamparos radiales (4) y sobre el conjunto envolvente exterior (7).the upper cover (6) located on the radial bulkheads (4) and on the outer envelope assembly (7).

Tanto los mamparos radiales (4), como el conjunto envolvente exterior (7) y la cubierta superior (6) están conformados a partir de paneles planos que se disponen unidos entre sí, mientras que la cubierta inferior (3) está formada por un elemento plano tal y como se representa en la figura 4. En la figura 5 se ofrece una configuración alternativa en la que la cubierta inferior (3) también está formada por paneles planos unidos entre sí.Both the radial bulkheads (4), as well as the outer envelope assembly (7) and the upper cover (6) are formed from flat panels that are joined together, while the lower cover (3) is formed by an element plan as shown in figure 4. In figure 5 an alternative configuration is offered in which the lower cover (3) is also formed by flat panels joined together.

La configuración a partir de paneles planos que se disponen unidos entre sí da lugar a un peso y volumen de soldadura menores que la configuración mediante un elemento plano reforzado por un sistema de emparrillado. En el caso de la cubierta inferior (3), en los espacios huecos, iría dispuesto un sistema de enjaretado para permitir el acceso a la pieza de transición (2). La carga vertical sobre la cubierta inferior (3), en este caso, correspondería solamente a la carga de paso sobre ella.The configuration from flat panels that are arranged together gives rise to a lower weld weight and volume than the configuration by means of a flat element reinforced by a grid system. In the case of the lower cover (3), in the hollow spaces, a lattice system would be arranged to allow access to the transition piece (2). The vertical load on the lower cover (3), in this case, would correspond only to the load passing on it.

Asimismo, la mayor parte de los elementos constituyentes son iguales entre sí, y en el menor número, tanto como sea posible, en línea con una filosofía de producción en serie.Likewise, most of the constituent elements are equal to each other, and in the least number, as much as possible, in line with a philosophy of serial production.

Adicionalmente, la pieza de transición (2) comprende una prolongación (8) de las patas de la celosía que se unen con los elementos constituyentes de la pieza de transición, que correspondan. Más específicamente, la prolongación (8) de las patas de la celosía se sitúa en la confluencia de un mamparo radial (4) con el conjunto envolvente exterior (7), concretamente en la confluencia de dos paneles planos del conjunto envolvente exterior (7) y un mamparo radial (4).Additionally, the transition piece (2) comprises an extension (8) of the lattice legs that join with the constituent elements of the corresponding transition piece. More specifically, the extension (8) of the lattice legs is located at the confluence of a radial bulkhead (4) with the outer envelope assembly (7), specifically at the confluence of two flat panels of the outer envelope assembly (7) and a radial bulkhead (4).

La estructura soporte resultante representada en la figura 1, es decir, la pieza de transición (2) y la estructura en celosía (1), es especialmente adecuada para turbinas de eólica marina en el campo de 5 a 8 MW y profundidades medias a altas (35-55 m).The resulting support structure shown in Figure 1, that is, the transition piece (2) and the lattice structure (1), is especially suitable for offshore wind turbines in the field of 5 to 8 MW and medium to high depths (35-55 m).

Asimismo, es adaptable a formas diferentes de pilotaje: pilotes (piling) o recipientes de succión (suction buckets). Posee también la ventaja de que las operaciones de manejo, izado e instalación, se facilitan a partir de un sistema sencillo y eficiente de elementos de izado que comprende cáncamos integrados en los mamparos verticales de la pieza de transición (2). It is also adaptable to different forms of piloting: piles or suction buckets. It also has the advantage that the handling, lifting and installation operations are facilitated from a simple and efficient system of lifting elements comprising integrated eyebolts in the vertical bulkheads of the transition piece (2).
